Abstract: L'invention concerne un détecteur de gaz permettant de détecter un changement de concentration d'un gaz spécifique tout en réduisant ses effets sur un environnement, notamment sur la température, l'humidité, et la vitesse d'écoulement d'air; et un système de ventilation d'automobile. Le détecteur de gaz (10) et le système de ventilation (100) utilisent un élément de capteur (11) de gaz dont la résistance de capteur Rs varie avec la concentration d'un gaz tel que Nox.

On détermine une valeur de base B(n) à partir de B(n) = B(n-1) + k1{S(n) - B(n-1)} ainsi qu'une différence D(n) = S(n) -B(n). Lorsque la différence dépasse un seuil de concentration prédéterminé du fait d'une augmentation de la concentration du gaz, un signal indiquant une concentration excessive est généré de façon à fermer un étrangleur (34), et une valeur de base B(n) est déterminée à partir de B(n) = B(n) + k2 {S(n) - B(n-1)} à l'aide d'un coefficient k2 inférieur à k1.

Inventor: SHARPE DAVID C
IPC: G06F17/27
Filed: 2002-06-18
Abstract: A method for comparing data, and in particular character data, is disclosed.  Two pieces of data are compared to determine if they are within an equivalence class based on using a dictionary sort order table with a non-unique collating sequence.  If so, the pieces of data are compared using a dictionary sort order table with a unique collating sequence. The comparison method may be implemented within a sorting module that receives an input data set and then uses the comparison to compare two pieces of data in the input data set at a time. The sorting module uses the result of the comparison method to sort the input data set into equivalence classes. The results of a second comparison provides data sorted within equivalence classes. The sorting module may provide sorting services to a database management system or to a calling program.

Title: Suspensions of water soluble polymers in surfactant free non-aqueous solvents
Inventor: HARRIS WILLIAM FRANKLIN
IPC: C08L91/06
Filed: 2001-04-17
Abstract: Liquid water soluble polymer suspensions in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed water soluble polymer. The suspensions enable a user to rapidly add the suspension to water, being mixed at low speeds, without the formation of lumps or fisheyes and without generating fugitive dust in the process. The suspensions are environmentally safe and biodegradable. Unlike many other liquid polymer suspensions, the suspensions exhibit minimal oil or grease upon dilution. They contain no surfactants that can add to the oil and grease determination. The suspensions and the fluids produced by diluting the fluids to a working concentration of the water soluble polymer exhibit low toxicity to marine organisms and to humans. The suspensions can be manufactured from ingredients suitable for use in personal care applications such as cosmetics, shampoos and the like. The suspensions can be manufactured using ingredients suitable for use in indirect contact with food. The suspensions are also pourable at low temperatures. The suspensions are also suitable for use in the formulation of fluids suitable for use in hydraulic fracturing and other well applications.
